Abstract

An electrophotographic device and a density control method are disclosed. In the apparatus such as a color laser beam printer and a copier using an electrophotographic developing method, the invention obtains an optimum print output regardless of the remaining toner or other contamination by locating a density control module inside of a transfer body, and by providing a transparent window in a dielectric sheet formed on the exterior surface of the transfer body.

Description

technical field [0001] The present invention relates to an electrophotographic apparatus, such as a color laser printer and a color copying machine using an electrophotographic developing method, and more particularly, to an electrophotographic apparatus capable of accurately detecting a color tone formed on the surface of a photoreceptor in the entire light area. An electrophotographic device and a density control method thereof for obtaining an optimum printout of the density of an agent image. Background technique [0002] Generally, in an image forming apparatus using an electrophotographic developing method such as a color copier, a color printer, etc., a charge roller is rotated and uniformly charges a photoreceptor on the outer periphery of a photoreceptor drum with a high voltage. [0003] Moreover, the charged photoreceptor on the outer periphery of the photosensitive drum forms an electrostatic latent image by means of light emitted from a light source of an exposu...
